If you want to read the credentials again from the boto3 session then use the get_credentials( ) method. source_profile - The boto3 profile that contains credentials we should use for the initial AssumeRole call. If you specify an mfa_serial, then the first time an AssumeRole call is the client. credential provider was added in 1.14.0. If youre running on an EC2 instance, use AWS IAM roles. Example: This credential provider is primarily for backwards compatibility purposes You can get temporary credentials with STS.get_session_token. Specify this value if the trust policy of the role being assumed includes a condition that requires MFA authentication. This value affects the assumed role user ARN (such as arn:aws:sts::123456789012:assumed-role/role_name/role_session_name). If you do not provide this value, a session name will be automatically generated. With boto3 all the examples I found are such: I couldn't specify my credentials and thus all attempts fail with InvalidAccessKeyId error. Regardless of the source or sources that you choose, you must have AWS credentials and a region set in order to make requests. aws_secret_access_key, and aws_session_token. ec2_client = session.client('ec2') In order to take advantage of this feature, you must have specified an IAM role to use when you launched your EC2 instance. credential provider was added in 1.14.0. See the IAM Roles for Amazon EC2 guide for more information on how to set this up. Return the :class:`botocore.credentials.Credentials` object, associated with this session. can get a list of available services via You can then specify the profile name via the AWS_PROFILE environment variable or the profile_name argument when creating a Session.
